Evaluation of patients heart rate changes.
. Evaluation of patients QRS interval changes.
· Evaluation of patients response to drug therapy treatment.

The "Indications for Use" for the modified 300-2W is exactly the same as the predicate 300-2 device.

Device Description

The 300-2W is a Holter Recorder that records the ECG signal in the exact same manner as the predicate 300-2 device. The 300-2W transfers the Holter ECG from its memory in the exact same manner as the predicate 300-2. The 300-2W uses the same USB cable as is used by the predicate 300-2 to transfer the Holter file from the Holter Recorder to the Holter PC. The Holter PC program processes the 300-2W Holter ECG recording with the exact same software program as is used by the 300-2 predicate device. All of the Holter ECG screen displays and print pages are exactly the same when using either the 300-2W device or the 300-2 predicate device. The Holter report from which the physician makes a diagnosis is the exact same format when using either the 300-2W device or the 300-2 predicate device. The 300-2W uses the same firmware as the predicate 300-2 to record the Holter ECG data and to transfer the Holter recording to the Holter PC. The ECG signal in the 300-2W is the same ECG signal as the predicate 300-2. The Intended Uses of the 300-2W and the predicate 300-2 are the same. The Indications for Use of the 300-2W and the predicate 300-2 are the same. The Design Controls and Performance Standards for the 300-2W and the predicate 300-2 are from the same source processes. The manufacturing process has ISO 13485 certification.

The 300-2W and the predicate 300-2 are multi-day Holter recorders. Both the 300-2W and the predicate 300-2 use the same alkaline or lithium batteries that are off-the-shelf AA batteries. Both the 300-2W and the predicate 300-2 use off-the-shelf commercial memory chips. The 300-2W uses a larger capacity memory chip, and both recorders operate with the memory chip in the same manner. The larger commercial memory chips are now larger capacity and cost less money than 300-2 Holter ECG recorder of 2006. All Holter ECG recorders have auxiliary real-time ECG outputs. These auxiliary outputs have no effect on the safety, performance, Intended Use, or Indications for Use with either the 300-2W or the predicate 300-2. Both the 300-2W and the predicate 300-2 have two (2) auxiliary outputs. The traditional uses of these auxiliary outputs is to view the quality of the electrode application to the patient prior to leaving the doctor's office, or to see the operational ECG of the Holter recording. The 300-2W and the predicate 300-2 have the same USB auxiliary output. The 300-2W has a WiFi auxiliary output and the predicate 300-2 has a transtelephonic auxiliary output.

AI/ML Overview

The provided text describes a Special 510(k) Notification for the DMS 300-2W Holter ECG Recorder, claiming substantial equivalence to its predicate device, the DMS 300-2. This type of submission focuses on minor modifications that do not affect the intended use, safety, or effectiveness of the device. Therefore, the document primarily details the lack of new performance studies because the modified device is considered to have identical performance to the predicate.

Given this, the acceptance criteria and study information typically found in a traditional 510(k) submission for a new device's performance are not present in this document. Instead, the "acceptance criteria" are effectively met by demonstrating that the modifications (larger memory and an additional auxiliary output) do not alter the fundamental characteristics or performance of the ECG recording and transfer process, which aligns with the predicate device that was previously cleared.

Here's a breakdown based on the information available, acknowledging the nature of a Special 510(k):

1. Table of Acceptance Criteria and Reported Device Performance

The concept of specific "acceptance criteria" for performance in the traditional sense (e.g., accuracy, sensitivity, specificity for diagnostic claims) is not explicitly detailed for the 300-2W because its performance is asserted to be identical to the predicate 300-2. The acceptance criteria here are implicitly based on maintaining the same technical specifications and performance characteristics as the predicate.

Characteristic	Acceptance Criteria (from predicate 300-2)	Reported Device Performance (300-2W)
ECG Leads	3-Lead ECG	3-Lead ECG
Resolution	8-bit	8-bit
Recording Duration	30-day	30-day
Bandwidth	0.05 to 100 Hz	0.05 to 100 Hz
Common Mode Rej	>60 db	>60 db
Power Source	AAA Alkaline	AA Alkaline (Note: this is a minor difference, deemed not to impact performance and is a standard off-the-shelf component)
Average Current Drain	3 mA	3 mA
Event ECG Button	Yes	Yes
Operating Temperature	0 to 60 C	0 to 60 C
1 MV Input	1-CM Square Wave	1-CM Square Wave
Processing System	Premier II Holter	Premier II Holter
ECG Data Transfer	PC's hard disk	PC's hard disk
Additional Modifications	N/A (Predicate)	Larger capacity memory chip
	N/A (Predicate)	WiFi auxiliary output (instead of transtelephonic)

The document states: "The 300-2W records the ECG signal in the exact same manner as the predicate 300-2 device," and "The ECG signal in the 300-2W is the same ECG signal as the predicate 300-2." "Both the 300-2W and the predicate 300-2 have successfully passed TUV Rheinland CE Test Reports for Holter Recorders." "The enclosed TUV CE Test Report 15030071 001 shows that the 300-2W Holter Recorder passed all the test specifications for EN 60601=1-2:2007."

2. Sample size used for the test set and the data provenance

No specific "test set" in terms of patient ECG data is described or used for this Special 510(k). The evaluation is based on engineering and performance testing against standards, confirming that the modified components do not alter the fundamental ECG signal acquisition or processing. The TUV CE Test Reports (Sections 12 and 13, and document 15030071 001) are mentioned for confirming compliance with electrical safety and EMC standards, which do not typically involve patient data test sets in this context. The provenance of such testing would be from accredited testing laboratories (e.g., TUV Rheinland).

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

Not applicable. As described above, there is no clinical "test set" requiring ground truth establishment by medical experts for this type of special 510(k). The submission relies on technical conformity to established standards and the assertion of identical performance to a previously cleared device.

4. Adjudication method (e.g., 2+1, 3+1, none) for the test set

Not applicable for the same reasons as #3.

5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

Not applicable. The device is a Holter ECG recorder, not an AI-assisted diagnostic tool. Its function is to record ECG data, not to perform analysis or integrate with AI for reader improvement.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

Not applicable. The 300-2W is a hardware device for recording ECGs, and its data is processed by the "Premier II Holter system" (K062088), a separate software component. The 300-2W itself does not perform analysis or have an "algorithm-only" performance to be evaluated.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)

Not applicable, as no clinical performance study involving diagnostic accuracy or clinical outcomes was conducted for this Special 510(k). The "ground truth" for the device's electrical and physical properties is its conformance to engineering standards (e.g., EN 60601=1-2:2007) as verified by testing.

8. The sample size for the training set

Not applicable. The device is a hardware recorder, not a machine learning algorithm that requires a training set.

9. How the ground truth for the training set was established

Not applicable for the same reasons as #8.

Legally 510(k) marketed device to which Substantial Equivalence is claimed:

In October 2006, the FDA issued its 510(k) number K062959 for the DMS Holter Recorder, Model 300-2, which is the predicate device for this submission. The Regulation Number was 21 CFR 870 2800, and the Regulation Name was Ambulatory Electrocardiograph without analysis. The Regulatory Class was Class II, and the Product Code was 74 MWJ.

The subject of this Device Modification submission is the DMS Holter Recorder, Model 300-2W. The 300-2W is a minor modification to the predicate 300-2 Holter Recorder. The modifications are (1) increasing the size of the memory storage without affecting the characteristics of the stored ECG signal, and (2) including an additional auxiliary ECG output for the traditional realtime ECG viewing of the operational status of a Holter Recorder.

The history of the predicate 300-2 device is that this 300-2W is its first modification for a submission of a Special 510(k) submission.

Principle of Device Operation:

The principle of operation of a Holter ECG recorder is that a battery powered device is worn by a patient for the purpose of a 24-hour or longer ambulatory ECG recording on either a hospital in-patient or out-patient. After the Holter ECG recording is completed, the ECG data is transferred from the Holter ECG recorder to a PC that has a Holter ECG processing software program. From the PC, a Holter ECG report is generated for a qualified physician to review. Only a licensed physician can order the Holter ECG test.

Description:

{2}------------------------------------------------

predicate 300-2. The Intended Uses of the 300-2W and the predicate 300-2 are the same. The Indications for Use of the 300-2W and the predicate 300-2 are the same. The Design Controls and Performance Standards for the 300-2W and the predicate 300-2 are from the same source processes. The manufacturing process has ISO 13485 certification.

Both the 300-2W and the predicate 300-2 have successfully passed TUV Rheinland CE Test Reports for Holter Recorders. Both the 300-2W and the predicate 300-2 use the same ECG electrode cables. Both Holter recorders provide the physician with the same Holter ECG results. See Sections 12 and 13 for the TUV CE Test Reports.

The enclosed TUV CE Test Report 15030071 001 shows that the 300-2W Holter Recorder passed all the test specifications for EN 60601=1-2:2007; including Enclosure Electrostatic Discharge, Radiated Emission on the Frequency Range above 30 MHz, RF electromagnetic field immunity test, and Power frequency magnetic field.

A photograph of the 300-2W is listed as an attachment in the Pictures section 15.

The physical properties of both the 300-2W and the predicate 300-2 are the same. The Holter circuit board is housed in a plastic type casing. The devices are similar in size to a mobile phone. There is an input for connecting an ECG cable, and an output for transferring the ECG that is stored on a memory chip on the circuit board. It is not physically possible to connect the ECG Cable input and the ECG data transfer output at the same time. As in all Holter ECG recorders there are auxiliary outputs to view the ECG in a real-time ECG mode. The physical properties of the 300-2W have been thoroughly tested for safety and performance as shown in the attached TUV Test Reports.
